Anisotropy in EELS of TiS2

Experiments on the L₃, L₂ edges of TiS₂ have been performed using Electron Energy Loss Spectroscopy. To interpret the small anisotropy observed, band structure and multiplet calculations considering the D_3d symmetry of the titanium site have been used. Reasonable agreement is achieved with experiment since the splittings of the empty levels are very well reproduced. It is hoped that this will assist in assessing the importance of the d_z2 orbital in the intercalation of species in the van der Waals gap.
